Domain Cloning

Once a template system has been installed, that system can be cloned. virt-clone will automatically change the MAC address of your network device.

Cloning

Use the script below to clone your template.

domain_clone.sh 

   1 #!/bin/sh
   2 
   3 LVM_GROUP="vg2"
   4 NAME_ORIGINAL="stretch-template"
   5 LVM_NAME_ORIGINAL="kvm_${NAME_ORIGINAL}_vda"
   6 LVM_SIZE_ORIGINAL=`lvs /dev/${LVM_GROUP}/${LVM_NAME_ORIGINAL} -o LV_SIZE --noheadings --units B --nosuffix`
   7 NAME_CLONE="stretch-clone"
   8 LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"
   9 
  10 if [ $# -gt 0 ]
  11 then
  12         NAME_CLONE=${1}
  13         LVM_NAME_CLONE="kvm_${NAME_CLONE}_vda"
  14 fi
  15 
  16 if [ ! -e /dev/${LVM_GROUP}/${LVM_NAME_CLONE} ]
  17 then
  18         # create lvm partition
  19         lvcreate --size ${LVM_SIZE_ORIGINAL}B --name ${LVM_NAME_CLONE} ${LVM_GROUP}
  20 
  21         # clone the domain
  22         virt-clone --original ${NAME_ORIGINAL} --name ${NAME_CLONE} --file /dev/${LVM_GROUP}/${LVM_NAME_CLONE} --check path_in_use=off,path_exists=off
  23 else
  24         echo "${0}: refusing to overwrite existing domain"
